These toggle switches are rugged, high performance sealed switches
designed for use under severe conditions found in heavy equipment,
industrial control, marine and appliance applications. They are totally
sealed so the switch can withstand direct water spray and submersion,
even during operation. They are designed to meet the international
submersion specification level IP68. OTTO's front panel seal is
accomplished with an O-ring under the bat handle. However, now a
secondary visible bushing seal is offered as an option.
T7 series toggles are offered in single and double pole configurations.
Achoice of models are offered to handle power levels to 16 amperes,
1/2HP and low level electronic switching applications.
These toggles feature positive detent action for safe switching
operation. In conjunction with the unique OTTO snap-action switch
mechanism, the T7 series offers non-teasible contact transfer.
High contact pressure and superior contact wiping action of the OTTO
design makes the T7 series an excellent choice for switching loads from
logic level up to 16 amperes.
Mounting hardware provided includes two hex nuts, one lockwasher
and one keyway washer. An optional panel gasket is also available.
